## Abstract A method for evaluating the temperature dependence of fourthβorder elastic constants (FOEC) of NaCl as well as CsClβstructure alkali halides is developed on the basis of the phononβpressure theory. Eleven distinct values of FOEC for each alkali halide crystal are calculated at 0 K and a
